1982 Buick Tire Fitment Guide

1982 Buick vehicles use 11 sizes across eight models. Century and Skylark use 185/80R13 or 205/70R13, Skyhawk uses 175/80R13 or 195/70R13, Regal uses 195/75R14, 205/70R14, or 205/75R14, LeSabre uses 205/75R15 or 225/75R15, Electra uses 215/75R15 or 225/75R15, Estate Wagon uses 225/75R15, and Riviera uses 205/75R15 or GR70-15. Rim diameters span 13, 14, and 15 inches, so the model determines the starting point.

That means a buyer cannot treat 1982 Buick as one universal tire application. Confirm the model first, then confirm whether your car uses a 13-, 14-, or 15-inch wheel before narrowing the sidewall style or brand. Rim-width compatibility also changes by size, with examples such as 175/80R13 fitting 4.50 to 6.00-inch rims, 185/80R13 fitting 5.00 to 6.50-inch rims, 205/70R13 fitting 5.50 to 7.50-inch rims, many 14-inch Regal sizes fitting 5.00 to 7.50-inch rims, and larger 15-inch sizes generally working in the 5.5 to 8.0-inch range depending on the exact tire.

GR70-15 is an alphanumeric radial size used on the 1982 Buick Riviera. The lettered prefix identifies the tire's size class, the 70 indicates its profile series, and the 15 is the wheel diameter in inches. In current reproduction form, GR70-15 appears as a radial with a period-style bias-look presentation, and it comes in sidewall treatments such as pin-white-stripe and raised white letter.

That code matters because a Riviera owner may be choosing between a conventional metric radial look and a more era-specific alphanumeric presentation. If your car is being restored with close attention to 1980s personal-luxury styling, GR70-15 often better matches the visual language buyers remember from the period. If your wheel and vehicle were set up for a metric size instead, stay with the exact fitment your Riviera uses rather than assuming both 15-inch options are interchangeable without checking the wheel and the car's current setup.

No, 1982 Buick models do not use one shared tire size. Buick split the range by vehicle type, with compact models on 13-inch sizes, Regal on 14-inch sizes, and full-size cars plus the Riviera on 15-inch sizes. Even within a single model line, more than one size can apply, such as the Regal's three 14-inch fitments or the Electra's two 15-inch fitments.

That model-to-model variation is the biggest reason to identify the exact car before selecting a tire. A Century or Skylark owner is comparing two 13-inch metric radials, while a Riviera owner may be deciding between a 205/75R15 metric radial and a GR70-15 alphanumeric radial with period appearance cues. If the car has changed hands or been restored, checking the sidewall on the old tire and measuring the wheel diameter can prevent ordering a size that belongs to another Buick model from the same year.

1982 Buick tires cover a wide range of sidewall appearances. Depending on size, options include blackwall, narrow whitewall, wide whitewall, goldline, redline, dual redline, raised white letter, RBL, and pin-white-stripe. Full-size Buick applications such as 225/75R15 and 205/75R15 lean heavily toward traditional whitewall styles, while Regal and Riviera sizes add more expressive sidewalls such as redlines, raised white letters, and stripe treatments.

The right sidewall depends on the personality of the car and the way you want it presented. A formal LeSabre, Electra, or Estate Wagon usually looks most at home with a whitewall, while a sportier Regal or a personal-luxury Riviera can support more graphic sidewall choices without looking out of character. If authenticity matters, match the style to the car's trim level, market position, and restoration goal rather than choosing purely by tread size.

1982 Buick coverage includes Maxxis, BFGoodrich, Coker Classic, Michelin, American Classic, Tornel, and Goodyear. Brand choice depends on the exact size: for example, 185/80R13 comes from Maxxis, BFGoodrich, and Coker Classic; 205/70R13 is offered by Michelin; 225/75R15 comes from BFGoodrich, Coker Classic, and American Classic; and GR70-15 comes from Goodyear. Several 14-inch Regal sizes also span multiple brands and sidewall treatments.

That variety gives Buick owners room to match the car's character instead of settling for one generic look. Some brands emphasize traditional whitewall presentation, while others support blackwall, lettered, striped, or redline appearances that better suit a sport coupe or personal luxury coupe. Start with the exact size your Buick uses, then compare the brand families within that size by sidewall style, load capacity where shown, and the visual era you are trying to capture.

On the 1982 Buick Regal's 205/70R14 fitment, BFGoodrich Radial T/A and BFGoodrich Silvertown Radial differ most in sidewall presentation and speed marking. Radial T/A uses raised white letters and carries an S speed rating, which has a 112 mph ceiling, while Silvertown Radial appears in redline and dual redline versions. Their wheel fitment range is close, with the Radial T/A fitting 5.00 to 7.00-inch rims and the Silvertown radial versions fitting 5.50 to 7.50-inch rims.

That makes the decision more about the look and wheel match than about choosing one as universally superior. A Regal with a sport package or period street-machine flavor may lean naturally toward raised white letters or redlines, while a more formal car might steer you toward a whitewall in another Regal size. Before deciding, compare your wheel width to the approved range and make sure the sidewall treatment matches the way the car is being restored or driven.

Rim-width requirements vary across the 1982 Buick range. Examples include 175/80R13 at 4.50 to 6.00 inches, 185/80R13 at 5.00 to 6.50 inches, 195/70R13 at 5.00 to 6.50 inches, and 205/70R13 at 5.50 to 7.50 inches. Regal sizes include 195/75R14 at 5.00 to 7.00 inches, 205/70R14 at 5.00 to 7.50 inches depending on product, and 205/75R14 at 5.00 to 7.50 inches. Fifteen-inch Buick sizes generally span 5.5 to 8.0 inches depending on the exact tire.

That range is wide enough that wheel width should be checked before final selection, especially on cars that may have been upgraded or swapped over the years. A 15-inch wheel alone is not enough information, because a 205/75R15 tire and a GR70-15 tire do not necessarily share the same wheel-width range. Confirm both the wheel diameter and the wheel width stamped on the rim, then match them to the size you plan to run.

The 1982 Buick sizes here are overwhelmingly radial passenger-car applications, and tube-type markings do not appear on these products. The 205/70VR13 example is explicitly marked TL for tubeless use, while the other sizes are presented in typical tubeless passenger radial form without TT markings. That makes tubeless fitment the normal expectation across these Buick applications when used on wheels that are suitable for tubeless service.

The wheel still matters as much as the tire. If your Buick retains original rims that are in good condition and intended for tubeless radials, the setup is usually straightforward. If the car has older wheels with corrosion, damage around the bead seat, or any unusual restoration history, have the wheels inspected before mounting new tires. Good valve stems, a clean sealing surface, and proper balancing do just as much for real-world success as choosing the right sidewall style.

A 1982 Buick should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate sidewall cracking. Keep the tires inflated to a stable storage pressure, move the car periodically if possible, and avoid letting one part of the tread carry the full load for months at a time. Clean, dry floors and tire covers help reduce long-term weathering.

That advice matters even more for low-mile collector Buicks, because age usually ends a tire's useful life before tread wear does. Cars that sit for long periods can develop flat-spotting, pressure loss, and sidewall aging that is easy to miss until the first highway outing. If the car will be parked for an extended season, occasional rolling or using stands in a way that protects the suspension and tires can help preserve both ride quality and appearance.

Tires on a 1982 Buick should be judged primarily by age and condition rather than by miles alone. A collector car tire often needs close evaluation around the five- to seven-year point, and replacement becomes a serious consideration as it approaches ten years old, even if the tread still looks healthy. The date code on the tire sidewall is the best starting point for understanding actual age.

That timeline is especially important on cars such as a Riviera, LeSabre, or Estate Wagon that may see occasional highway use after long storage intervals. A tire can look cosmetically good and still have hardened rubber, internal aging, or cracking that changes how the car rides and responds. If the age is creeping up, combine the date-code check with an inspection for weather checking, bulges, uneven wear, and persistent air loss before trusting the car on longer drives.

Tires on a 1982 Buick should be checked before every drive and again before any longer road trip. Look for sidewall cracking, cuts, bulges, exposed cords, tread separation, and uneven wear, then verify air pressure once the tires are cold. Pay attention to how quickly the tires hold or lose pressure between uses, because collector cars often sit long enough for a slow leak to go unnoticed.

A routine inspection is one of the easiest ways to protect a vintage Buick from preventable roadside trouble. If your car uses a whitewall, stripe, goldline, or redline tire, inspect the decorative sidewall carefully as part of the process rather than focusing only on the tread. Any new vibration, pull, thump, or visible shape change deserves attention before the next outing, since those symptoms often show up before a failure becomes obvious.

A 1982 Buick Riviera falls squarely in the period when radial construction was standard for American personal luxury cars, and the fitments here reflect that with both 205/75R15 and GR70-15 radial applications. The GR70-15 size is especially tied to the era's alphanumeric tire language, while 205/75R15 represents the metric radial system that was also common by the early 1980s. Original-equipment branding could vary by market and build, so the construction type and correct size are the key first targets.

For a careful restoration, start by confirming which of those two sizes belongs on your particular Riviera before choosing a sidewall treatment. A car restored for factory-style appearance may benefit from the GR70-15 route if that is what the car was meant to wear, while another example may properly use the metric size. If originality matters beyond the basic size and construction, consult a Riviera specialist, period literature, or a marque club for trim- and build-specific confirmation.

Correct tire fitment matters on a 1982 Buick because judges and knowledgeable enthusiasts notice size, construction type, and sidewall style very quickly. A Skyhawk, Century, or Skylark wearing the wrong wheel diameter stands out immediately, and a Riviera or Regal with an off-character sidewall treatment can change the car's period presentation just as much as the wrong wheel cover. On many show fields, visual accuracy counts nearly as much as mechanical correctness.

That does not mean every show car must wear the same sidewall style, but it does mean the choice should match the model's personality and the goal of the build. A formal whitewall often suits Buick's larger luxury models, while a Regal may legitimately support more sporting treatments. If the car is headed for judged concours competition, ask the sponsoring marque club or event officials how strictly they score tire appearance, because standards vary from one event to another.

For a 1982 Buick Riviera in GR70-15, Goodyear GM Custom Tread and Goodyear Steelgard share the same basic alphanumeric radial fitment but differ in sidewall presentation and wheel-width details. GM Custom Tread appears as a pin-white-stripe version with a 7.0 to 8.0-inch rim range, while Steelgard appears in both raised white letter and pin-white-stripe forms, with examples covering 7.50 to 8.0-inch or 8-inch rims. Weight also varies, with examples around 29 to 30 pounds.

That makes the choice more about the exact period look and wheel match than about changing the Riviera's overall fitment category. If you want the most formal luxury appearance, the pin-white-stripe versions are the natural place to start. If your Riviera leans toward a sport-luxury presentation, the raised white letter version may feel more in character. Measure the wheel width before deciding, because GR70-15 products are not all approved for the same rim width.

1982 Buick tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their speed and load limits. The sizes here are all radial, with one GR70-15 category using bias-look radial construction, and marked speed ratings include S at 112 mph and V at 149 mph on certain products. Those limits exceed ordinary highway use, but tire condition and correct inflation still matter more than the number alone on a low-use collector car.

In real-world driving, the Buick's own age-related mechanical condition is often the more important limiter. Suspension wear, brakes, alignment, steering components, and old shocks can all affect highway stability before the tire reaches its rated ceiling. If the car has been parked for long periods, inspect the tires first, then make sure the rest of the chassis is equally ready for sustained speed. A fresh set of correct tires helps, but it does not override the condition of the vehicle around them.

Inflation pressure on a 1982 Buick should follow the factory recommendation for the car and the tire maker's maximum-rated pressure information for the exact product. Pressure and load figures vary by size: for example, 185/80R13 reaches 1,323 pounds at 35 psi on one product, 175/80R13 reaches 1,179 pounds at 35 psi, 205/75R14 reaches 1,532 pounds at 35 psi, 205/75R15 reaches 1,598 pounds at 35 psi, and some 225/75R15 products reach 2,094 pounds at 32 psi while others reach 1,874 pounds at 35 psi.

Those differences are why pressure should never be copied from one Buick size to another or from one brand to another without checking. Maximum sidewall pressure is not automatically the same as the ideal operating pressure for your car, especially on a lightly driven collector vehicle. Use the original manual or door-jamb guidance as the baseline for the vehicle, then confirm the exact tire's construction and rating so you are not overinflating or underinflating for the intended application.

Before a longer trip in a 1982 Buick, inspect every tire for cracks, cuts, punctures, bulges, uneven tread wear, and signs of age hardening, then confirm cold inflation pressure and verify that the spare is usable. Check valve stems, wheel balance if the car has shown vibration, and overall tread condition at all four corners. A car that has been parked for weeks or months deserves an especially careful walk-around before it returns to highway speed.

The tires are only one part of the preparation, but they are the part touching the road. A full pre-drive check on a car of this age should also include brakes, fluids, belts, hoses, steering response, and lighting, because a well-preserved Buick still depends on 1980s hardware and maintenance habits. If the tires pass inspection but the car feels unsettled, wanders, or shakes on a short test drive, stop there and sort out the chassis condition before committing to distance.
